hi Frank,

Below is my program,

If RenderFormat to ".Net" it Not able to work at click events on each data point but it able to changes on Datagrid.

If RenderFormat = "Image" it able to work at click events on each data point but it Not allow me to changes on Datagrid.

Actually i would like to perform these both which is click events on each data point and allow to changes on Datagrid. Is there possible??

A click on the client will not always cause a Click event to be fired in the server, only clicks made on points are sent back to the server as a PostBack/CallBack. A MouseClick event will fire on the client everytime.

You can capture client-side event using JavaScript. For example:

<SCRIPT  LANGUAGE="JavaScript" FOR="Chart1" EVENT="MouseDown(sender,eventargs)"><!-- Chart1.AllSeries.PointLabels = true;--></SCRIPT>
